Product Overview
Iris 'Roy Davidson'
This sterile hybrid of yellow flag and an unknown iris is a great replacement for yellow flag iris, which we no longer sell due to its invasive nature. Roy Davidson is a far superior bloomer, with bright yellow flowers that have attractive brown veining. Roy Davidson comes up earlier and blooms earlier than yellow flag, and in mild climates will not go dormant. The foliage is glossy, and the tops of the leaves tend to curve over.
